MILK-STRAINER.

Specification of Letters Patent. I

Patented Aug. 3, 1920.

Application filed January 19, 1920. Serial No. 352,402.

To all whom it may concern:

Be it known that we, WILLIAM T. BILL- was and FREMONT So iRYvEn,citizens of the United. States, residing at Ithaca, in the county ofTompkins, State of New York, have invented a new and useful Milk-Strainer, of which the following is a specification.

vices, and more particularly to devices especially constructed forstraining milk in the production of condensed milk.

The primary object of the invention is to provide a device of thischaracter ca-' pable of application to a pipe line between the supplyand discharge ends thereof, thus insuring the straining of the fluidpassing through the supply pipe.

A further object of the invention is to provide a straining deviceincluding a re movable straining element which may be I 1 within thescope of. what is claimed, without departing from the spirit ofthe'invention. j

Referring to the drawing: Figure 1 illustrates a longitudinal. sectionalview through a straining device con-;

structed in accordance with the present invention, and

Fig. 2 illustrates atransverse sectional view taken on line 22 of Fig.1..

reference character 5 designates the headof the straining device. thesame being pref-- Referring to the drawing in detail, the

erably circular in plan, the lower side thereof being provided with adownwardly extending annular flange 6 for the purpose of supporting thebody portion 7 of the strainer proper.

This strainer body 7 includes a relatively long tubular section havingits. upper end I fitted within the head, the upp r end engaging theannular flange 6,and having connection therewith through the medium;

ber 10,

openings in the flange and the upper end of the body 7.

An annular shoulder 9 is also provided within the head 5, and adjacentthe upper end of the body 7, for purposes to be hereinafter more fullydescribedyit being understood that this shoulder lies in a plane equalto the plane of the'upper'surface of the upper edge of the body 7.

The lower end of the body 7 extends into the upper end of the funnelshaped memand' has connection therewith through the medium of the bolts11, whereby movement of the funnel shaped member 10 is absolutelyprevented, the lower end of the funnel shaped member 10 havingconnection with the discharge pipe 11"; for

conveying or directing the fluid passing through the straining body, toany suitabletank or device associated with the filtering mechanismforming the present inven tion.

Supported within the body 7 of the strainer. is a removable filteringmember 12 which includes a tubular member of a length equal to thelength of the body 7, the tubular member being supported'in spacedrelation with the body 7 to provide. a passageway between the filteringings 9' formed in the walls thereof. which openingsv providecommunication between the interiorof the stramlng member and thebody/member 7, so that the material passing through the straining membermay.

pass through the openings 9, and into the funnel shaped member where thesame may becarried off by means of the discharge pipe 11.

Acircular inetallicplate 14 is provided with. a central opening 16, thewalls of which extend downwardly as at 16 to pro- .vide anannular'flange 17 for accommodatto receive the pin 13: formedon theupper end of the straining member 12, whereby the straining member 12 isremovably supported within the body/7 of the straining dQVlce, portionsof the circular platev having engagement with the Shoulder 9 to preventmovement of the straining member 12 with relation to the body 7 thereof.

From the foregoing it is obvious that portions of the circular plate 14:surrounding the central opening 15 provide means for closing the upperend of the annular passageway between the straining member 12 and thebody portion 7. r I

Pins 14: are also provided on opposite sides of the straining member 12adjacent the lower end thereof, which pins operate in the slots 16formed in the upwardly extending flange 15" formed on the removablebottom member 30. From the foregoing it is obvious that the strainingmember 12- may be readily removed and cleaned.

In order to facilitate the removal of the inner straining member 12, ahandle 18 is provided which has its ends secured to the circular plate14 by means of the rivets 19.

The upper-portion of the body 5, is open to permit easy access to theinterior of the filtering body 7, there being a removable cover 20employed in connection with the body 5 for closing the opening toprevent the fluid passing into the body 7 of the.

filtering device from splashing or finding its way from the body 5, andat the same time this cover 20 prevents foreign matter from entering thebody Arms 21 extend outwardly from the side walls of the opening formedin the upper portion of the body 5, and have pivotal connection withtheupwardly extending therefore obvious that when the cover '20 ispositioned over the opening in the body 5, the arms 22 are moved topositions as indicated by Fig.1 of the drawing, where upon the operatinglevers are rotated to cause the heads 25 thereof to contact with thelugs 24, whereupon the cover is secured to the body 5 againstdisplacement, and if it becomes necessary to remove the cover 20 inorder that the filtering member 12 may be removed for cleaning purposes,it is only necessary to operate the levers 26 in the opposite directionto permit the arms 22 thereof to swing downwardly and outof contact withthe walls of the slots 23, it

follows that the cover 20 may now be lifted. from the body 5 by graspingthe handle 27 Relatively short pipes 28 extend from opposite sides ofthe body -5 and provide means for receiving the endsof the supply pipes29, which have connection with a suitformed in the side walls of thestrainin D member 12. The fluid is now freed of all foreign substances,and the strained fluid is directed to suitable tanks or vats where thesame may be carried off at the will of the operator.

Having thus described the invention, what we claim as new is 1. In astraining device, a head, a body portion depending from the head andhaving a funnel-shaped member connected to the lower end thereof, anannular shoulder formed at the upper end of the body-portion, astraining device comprising a relatively long tubular member havinglaterally extending pins secured adjacent to the upper end thereof, acircular plate resting on the shoulder and having a depending flange,said flange having slots formed therein, said slots adapted to receivethe pins of the straining, member for removably securing the strainingmemberto the circular plate, and a removable bottoin supported on thelower end of the straining member. 5

' 2. In a straining device, a head,- a cylindrical body portion securedtothe head and in communication therewith, a funnelshaped? dischargemember secured to the lower end of the body portion, a removablestraining memberincluding a circular plate supported adjacent the upperend of the body portion, a tubular perforated member removably securedto the circular plate, the walls of the tubular member-being disposed inspaced relation with the inner walls of the body portion, laterallyextending pins formed at the base of the tubular perforated member,abottom memher having upwardly extending flanges, said flanges beingprovided with slots adapted to receive the pins, for removably securingthe bottomi member to the tubular memher, and means having connectionwith the circular plate for removing the straining member; I

' In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in the presence of two witnesses.
